Navaid Autopilot woes

[Tom]

Hi Folks,

My VE has a navaid AP,, and it has been working great.

Recently I changed out the servo with a NEW unit (the old one was starting to show wear in the main shaft bushings and gears) 

I cant seem to get it to settle down, all it does is shake the stick! 

I have the feedback trim pot set correctly on the proper "Null" and all other settings dont seem to help.

The system gain, even when turned down all the way doesnt seem to help,

Any suggestions?

Tom, where did you find a new servo?  I have a backup head but could use a servo too....
On another forum recently they said Trio would take a look at a Navaid head to troubleshoot, might try them for your servo issue......?

I bought the servo on ebay years ago,   the only reason I bought it was to have a spare.

What I might do it re build the other servo I have, and then re install it.
